Tree Listening

Have you ever thought what goes on behind the bark of a tree? Join Alex Metcalf from The Tree Listening Project as he uses highly sensitive microphones to make audible the inner workings of trees. Hear the rumble of the tree moving and the popping of the water as it mixes with air on it’s way up through the Xylem tubes just behind the bark, the very life of the tree surging up from the roots towards the leaves.
